A current was passed for $10$ hours. $10.8\ g Ag$ was deposited at cathode in $(III)$ electrolytic cell during electrolysis if current efficiency is $50\%.$
If $Z_1,$ $Z_2$ and $Z_3$ be the electrochemical equivalent in the formation of $H_2, Cu$ and $Ag$ respectively, hence $Z_1 : Z_2 : Z_3$ would be

$A(g)\,\xrightarrow{{{K_1}\, = \,2\, \times \,{{10}^{ - 3}}\,\,{S^{ - 1}}}}2B\,(g)$
$A(g)\,\xrightarrow{{{K_2}\, = \,1\, \times \,{{10}^{ - 3}}\,\,{S^{ - 1}}}}C\,(g)$
